Generally, commercial satellites use C-band and Kuband, but because of the rapid growth of satellite services and congestion of lower frequencies bands, more and more commercial applications are being promoted for Ka-Band. In order to use Ka-Band for satetllite communication in tropical areas, there are several issues that have to be considered. One of the disadvantages of Ka-Band is it susceptible to be attenuated by rian and the earth's atmospheric conditions such as gas, clouds ,and ice particiles. This paper is aimed to evaluate the performance of Ka-Band wireless communication system in tropical area by comparing several channel coding schemas.
